The 1-5 scale estimates potential property damage from sustained wind speed.

Category 3 or higher is considered a major hurricane.

A hurricane warning states that tropical storm winds of at least 74 mph are expected within 36 hours.

hurricane development

Tropical disturbances: Cloud plumes develop into a group of thunderstorms.

Tropical Depression: Thunderstorms intensify, with maximum sustained winds of 38 mph or less.

Tropical Storm: Maximum wind speed between 39-73 mph. During this time, the storm becomes more circular in shape, with the winds rotating around a calm center, known as the eye. That’s when a storm is named.

Hurricane: Winds reach a maximum sustained wind speed of 74 miles per hour.

Names

There are 10 regional lists of names around the world: Atlantic Ocean, Northeast Pacific, Central North Pacific, Western North Pacific/South China Sea, Australian Region, Nadi, Port Moresby, Jakarta, Southwest Indian Ocean and North Indian Ocean.

The use of female names for Atlantic storms was the practice until 1979, when male names were added to the mix.

Names associated with storms that have caused death and/or significant damage have been removed from the list. After the 2021 season, the name Ida retired. Some of the other names that have been removed include Camille (1969), Andrew (1992), Floyd (1999), Katrina (2005), Ike (2008), Sandy (2012), Maria (2017), and Eta (2020). Once the name is removed, another name replaces it.
